Abstract:
With numerous enterprise architecture management (EAM) methodologies, frameworks,
and tools, there is still no universally accepted standard on what Enterprise Architecture
(EA) really means to practicing architects. Traditionally practitioners concentrated on
specific aspects of EA, such as tools, repositories, components and frameworks. However,
little attention was given to the architect, who completes this trio of system perspectives
(people, process & technology). This thesis reports on the research findings from multiple
studies that investigated diverse factors and attributes that are associated with enterprise
architects; the belief systems of enterprise architects as they pertain to enterprise
architecture and enterprise architecture management; the behavioural styles of enterprise
architects which they follow within their socio-technical environment, as well as enterprise
architect profiles, representing a specific enterprise architect viewpoint. The enterprise
architect belief systems affect the worldview and ultimately the school of thought of the
practicing architect. Similarly, the role and competency of enterprise architects operating
within their working environment affects their behavioural style.
This thesis made use of design science research as a foundational strategy, making use of
various research methodologies including a systemic literature review and qualitative
surveys and the use of the framework for the evaluation of design science research (FEDS).
The design science research strategy allowed for the development of the design artefact as
well as its technology-based implementation, the Daedalus Instrument for Architects (DIA).
DIA can be used in conjunction with existing EA frameworks and methodologies, such as The
Open Group Architecture Framework (TOGAF) for the understanding of architects on why
they operate and perform architectural designs in the way they do. The findings may assist
enterprise architects and EA stakeholders concerned with having the right calibre of person
acting as an enterprise architect fulfilling a specific architecture function within an EA team
or EA practice.
